Composite beam having tie anchor embedded in a concrete

摘要

steel concrete composite beam of the present invention is used to form the concrete member as the there is no need for a separate formwork, the beam and the slab is relates to a composite beam for holding joint between the structurally stable without the need for a separate front end consolidated, and more particularly the twisting of the open cross-section by filling in a cross section of the concrete tie anchor is installed, solve the problem and fill half Thai PC free from the problem of plate buckling chapter in the construction phase of the composite beam anchor. PC synthesis see tie anchor lower plate half filled with two side plates extending upwardly from both ends of the lower plate and each of the horizontal direction of the blade extending outwardly from the two side plates in accordance with the preferred embodiment of the present invention consisting of a supporting member; Configured at both ends of the plurality of holes for concrete perforated top plate and the top plate with two inclined extending downward is coupled to the upper end surface of the supporting member constraining member for the closure section; Tie the top of this section if the anchor restraint member has a height greater than the upper plate section restraint member is bonded to a reinforcement reduces the stress resultant buckling restraint member chapter of the section; Are arranged at regular intervals in the longitudinal direction in the upper surface of the lower plate support members vertically coupled to the reinforcement plate, the rebar through the through groove consisting of tensile reinforcement is arranged in the reinforcement plate to the lower plate; Curing is poured inside the support member and the lower tie rebar concrete anchors are buried half fill restrained; characterized in that it contains a ;
